Question about open_device.

Hi all,
I was checking the function open_device in the file usb-libusb.c and have seen that, either when usb_claim_interface or usb_set_altinterface are called, it does:
while (usb_claim_interface(printer->handle, number) < 0)
{
if (errno != EBUSY)
fprintf(stderr, "...");
goto error;
}
So it seems that it will jump to 'error', also when errno == EBUSY, so it won't execute the loop anymore.
Regards.
